WAVE MOTION SIGN TRANSMISSION |
摘要 |
<p>A transmission system for louver type signs wherein the signs consist of a plurality of multiple faced louvers having indicia defined thereon and the side-by-side relationship of the louvers permits pre-selected faces to define a completed image. The adjacent transmissions are operated by a constantly rotating drive shaft and the louvers may be simultaneously rotated or may sequentially operate in a delayed manner wherein the indicia on the louvers is progressively revealed in a "wave" manner. The drive shafts of adjacent transmissions are interconnected and a plurality of transmissions are operated by a single constantly operating motor drive source, and in the disclosed embodiment, a complete rotation of the transmission's drive shaft produces one-third of a rotation of the output shafts operating the louvers. A positive detent lock operated by a cam formed on the drive shaft gear produces a positive locking of the output shaft and the position of the louver, and the detent is automatically engaged and released in the proper sequence by the cam.</p> |
